Twill whom t may; concern:

Be it known that i, FRAME 5, Tiiziimiiii o citizen of the United Sietes, residing in @he cit-,y amd County of iiaiioisco and @wie of California, have invented new and use fui improvements iii Romify Eogiiies which ithe following is e speeiceiion'.

This invention reieies io o misery engine.

The object of the present invention is izo provide o simpie, subsimmiiei9 eheopiy menuaetureci steam engine of the otejiy type, and particularly to provide o moi'e efiieien; form of piscon and rotoli'.

Another? object of the invenzioii. is im provide e novei form of drive oi connection between the piston and ioiior".

when one or another of the pistons moves into engagement with latch 23; exhaust port 27 being provided for this purpose. Latch 23, together with cam 22, may be of any suitable width. lt is normally springactuated, so as to project out into the path of the pistons, but is automaticallyreleased when the movingpiston moves into engagement with the stationary piston; the impact of the traveling piston being cushioned by extension 12 passing into recess 13. The exhaust does not take place until the stationary piston has been released and the movable piston has become interloclred with latch 23. .Valve 21 is then in position Where the live steam port 21a will communicate A continuous drive is thus transmitted to the rotor by each piston in consecutive order, one acting as a driver while the other remains stationary and forms a head `against .which pressure is exerted to permit the moving piston to transmitpower to the rotor. Latches 17 may be thrown into engagement with any one of the notch-like recesses 19 formed in the rotor. Slippage between the rotor and any particular piston can thus take place without a'decting the operation of the engine.

rlhe contacting surfaces of the rotor and main casing are preferably ground to form a tight connection at this point; the rotor being held in contact with the main casing, first by the pressure `of the outer cover against the hub of the rotor, and secondly, by pressure of the leakage steam which accumulates between the cover and the rotor; any further escape of steam being prevented by providing stufling boxes 3 and LP.

The engine here shown is simple and substantial in construction and efficient in operation, as leakage steam is entirely eliminated. The long piston stroke furthermore adds to the eiciency of the engine, as complete expansion is permitted.

The ymaterials and finish of the several parts of the apparatus are such as the eX- perlence and judgment of the manufacturer may dictate.

l wish it understood that various changes 1n form, proportion and minor details of construction may be resorted to Within the scope of the appended claims, and that I do not Wish to limit myself to the speciic desiUn and construction here shown.

claim and desire to secure by Letters Patent is:

1. 1n Ja rotary engine, a casing, a rotor connected-to the casing and forming an an# f aviiig thus described my invention, what v ing, said casing having a pocket, a spring pressed pivoted latch in the pocket having a cam which with the latch proper projects into the chamber, a pair of pistons in the chamber, each piston having a pocket and a steam port which leads from the pocket through the adjacent piston end, a pivoted latch in each piston pocket, each piston having a chamber' in one end thereof, and a plunger connected to the opposite end of each piston and receivable in the chamber of the other piston, said pistons having re cesses in their peripheries arranged to one side of the latches thereof to receive the latch of the casing, and said rotor having a circular series of depressions in its inner circumference to receive said latches of the pistons.

2. ln a rotary engine, a casing, a rotor connected to the casing and forming an an nular chamber in conjunction with the casing, said casing having a pocket, la spring pressed pivoted latch in the pocket having a cam which with the latch proper projects into the chamber, a pair of pistons in the chamber, each piston having a pocket and a steam port which leads from the pocket through the adjacent piston end, a latch in each piston pocket, and means whereby steammay enter` each pocket and act against the 'rear face of the latch to move the latter outwardly, said rotor having depressions to receive the piston latches, and said pistons having recesses in their peripheries arranged to one side of the latches thereof to receive the latch of the casing.A

3. In a rotary engine, a casing, a rotor connected to the casing and forming an annular chamberin conjunction with the casing, said casing having a pocket, a spring pressed pivoted latch in the pocket having a cam which with thelatch proper proj ects into the chamber, a pair of pistons in the chamber, each piston having a pocket and a steam port which leads from the pocket through the adjacent piston end, a pivoted latch in eaoh piston pocket arranged so that the steam which enters the pocket will not upon the rear face of the last named latch to move the same outwardly, said rotor having depressions to receivel the piston latches and said pistons-.having recesses in their peri iheries arranged to one side of the late es thereof to receive the latch of the casing.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
